I totally get the point of the OP.
He/She is probably spending thousand, or Thousands, more then they would to stay at POR or any Mod for that matter. IF the appeal to the Poly is the monorail, which I have seen like a hundred deluxe snobs say exactly those words "The poly is worth the extra money because of the Monorail" ... Then yes, I'd be demanding a switch and a refund of the difference, and maybe some compensation for the need for the switch. Or, just compensation equaling the difference between the Poly and POR.
They can't sell you a trip, including amenities, then you get there, have paid, and those amenities aren't offered.
That would be like buying a car, and when its delivered getting a different interior then you ordered (one not nearly as good) you don't say, well, its still the car you ordered.
The OP paid for the Poly, including the Monorail (since that's a MAJOR portion of what you are paying for at the Poly), and if the monorail isn't running the way its supposed to, the way its advertised and sold as, then the OP should be compensated.
